[PATCH 1/30] mm: Export init_mm for MIPS KVM use of pgd_alloc()

[James Hogan <james.hogan@imgtec.com>]

Export the init_mm symbol to GPL modules so that MIPS KVM can use
pgd_alloc() to create GVA page directory tables for trap & emulate mode,
which runs guest code in user mode. On MIPS pgd_alloc() is implemented
inline and refers to init_mm in order to copy kernel address space
mappings into the new page directory.
